Question about suspension upgrades

Just took a look under mine as winter has subsided for a bit. Apparently one of my corksport adjustable end links pulled out at some point!!!

Crazy.
Bummer! I hope Corksport makes good and replaces it.

How old are those end links?
 
Approximate [stock] lengths:

Front: 290mm
Rear: 150mm
Tein Adjustable Sway Bar Link Rods

I would get the M10-290 for up to 2" and the M10-335 for a 2-3" drop. For the rear, you want the M10-120 for 2". If lowering more than 2", you'll want the M10-100.

Looks like you can order these ^^ direct from Tein:
Front: M10-290 290-350mm - up to 2" drop
Front: M10-335 335-395mm - 2-3" drop
Rear: M10-120 120-140mm - up to 2" drop
Rear: M10-100 100-120mm - 2-3" drop

Wish the reviews on these https://www.amazon.com/dp/ (commissions earned) weren't so bad
Front: SB-TR-260-10_13 - 310-370mm
Rear: SB-TR-16 - 110-140mm

Think I'll get the Tein links. Any other brands to checkout?
 
I wish I had people to ask. It took me months of research to figure out my ride quality problems and find what I needed to order, including reading BMW forums and spending time under the car to figure it all out. There aren't many options for these cars or detailed discussions on these parts. I hope people find these discussions helpful going forward.
 
@N7turbo @AL Cx5 agree and really appreciate all the research, experimentation, and willingness to share the knowledge because otherwise everyone would be on their own trying to figure this stuff out.

Feels like I’m one step closer to having my GT-style build complete which like @AL Cx5 includes a tune but also a full audio/acoustic overhaul which added significant weight (fiberglass subs/deadening/mass loaded vinyl). Hoping to shed some of that weight with coilovers, at least up front.

Speaking of coilovers, I’m currently trying to decide between BC racing vs Ceika M1. I’m dealing with some pothole ridden streets and lots of speed bumps which is making me consider Ceika M1 with a Comfort build (rennlist review). It sounds like BC and Ceika may use the same underlying parts and that Ceika are just more customizable.

Currently considering this setup - with comfort dampers dialed on the firmer side. Need to figure out spring rates and if I should get helper springs. Will have Hardrace front/rear ASB likely set to soft on both.

Any suggestions on spring rates and if helper springs are worth it?
 
I spoke with them the about the helper springs. The way they describe them is nothing like any other company. Normally "helper springs" just keep load on the main spring so it never comes loose at max extension. So idk if they are fos or if there's something different about them.

For spring rates, I'm eyeing 4K front, 6K rear. If you're doing sway bars, you probably don't want to go stiffer than that if this is a daily on city streets. Their default will be 6K/6K.

The only unknown to me about the rates is making sure it's enough to prevent bottoming out with a 2" drop.
